James McAvoy And Nicholas Hoult Play Fight On Set

James McAvoy and Nicholas Hoult played with BB Guns on the set of 'X-Men: Days of Future Past'.

The 35-year-old actor and his co-star - who is dating Jennifer Lawrence - had a ''lot of fun'' with the popular children's toys when they had hours to spare in between takes.

Speaking on US Chat show 'The View', James explained: ''There was a lot of fooling around - you know, not that kind of fooling around.

''There was weirdly a lot of fighting. We had a lot of BB Guns and things like that. Myself and Nick Hoult, who plays Beast, went to a big Canadian superstore and bought those BB Guns ...

''You know what it's like when you've got five - six hours between special effects shots and things like that. You can sit around and get depressed or you can try and shoot each other. It was fairly intense, it was a lot of fun. ''

While he had a fun on set, it seems doing promo can be just as entertaining.

He recently revealed he almost crashed a helicopter on his way to Sao Paulo after the pilot invited him to take control of the aircraft

The hunk said: ''I looked at him and thought he was joking. And then he took his hands off the joystick...

''I did think the pilot was insane but I like that kind of crazy. So I was holding the joystick and was thinking this is doable, this was fine and then the slightest movement and then it would go shwwm......I think the pilot s**t himself and took back the controls. ''
